[0047] The function of the waterproof device of the opening drive unit constructed as described above will be described below.
[0048] The water falling from the side of the upper heald frame 3 is blocked by a horizontal baffle 35 provided in front of the heald frame 3, and is guided downward. This prevents water from splashing to the side of the fabric on the beam (not shown) installed in the front of the machine. And it is blocked by the weaving shaft baffle 36 arranged behind the heald frame 3 and guided downward. This prevents water from splashing to the side of the weaving shaft (not shown) installed behind the machine. The lower end of the bobbin baffle 36 hangs down to the rear end of the upper groove 37, and the upper groove 37 is inclined forward, so the water guided to the bobbin baffle 36 and flowing to the upper groove 37 flows to the middle groove 38 along the inclined surface Focus on one side.
[0049] In addition, the water directly falling from above to the side of the upper tank 37 also flows to the side of the middle tank 38 along the inclined surface and is collected.
[0050] In addition, the water is blocked by the partition walls 41b and 42b provided on the periphery of the upper tank 37 and does not leak to the outside. In addition, the lower end of the horizontal baffle 35 is set to hang down to the intermediate groove 38, so the water guided to the horizontal baffle 35 is immediately concentrated in the intermediate groove 38.
[0051] The water concentrated at the drain ports 38b and 38c formed on the intermediate tank 38 is immediately discharged to the drain 40 via the hoses 39a and 39b installed on the drain ports 38b and 38c, so the water will not fall on the drive of the opening drive part. Wet the parts. In addition, it is possible to prevent the water remaining in the aforementioned intermediate tank 38 from overflowing during machine operation or the like to wet the transmission components of the opening drive unit, or endanger people. In addition, since the waterproof cover is only provided above the opening drive part, it is open to outside air in the front and back and left and right directions, and moisture will not be retained, and the state of the opening drive part can be visually confirmed from outside the machine without removing the waterproof cover .
[0052] If the water-proof device of the opening driving part in the water jet loom of the first embodiment is adopted, the following effects are obtained.
[0053] (1) Since the upper groove and the middle groove are used to block, concentrate, and discharge the water falling from above, the transmission parts of the opening drive part will not be wetted, and the aforementioned transmission parts will not corrode early.
[0054] (2) By making the other end of the hose installed on the drain port formed in the middle tank face the drain ditch, the water accumulated in the drain port can be quickly discharged to the side of the drain ditch through the hose, which can prevent the remaining water from working on the machine If it overflows from time to time, it will wet the transmission parts of the opening drive part, or endanger people.
[0055] (3) The horizontal baffle can be used to prevent water from splashing to the side of the woven fabric wound on the beam, and the weaving shaft baffle can be used to prevent water from splashing to the weaving shaft.
[0056] (4) Since the waterproof cover is only provided above the opening driving part, it is open to the outside air in the front and rear and left and right directions, no moisture will be retained, and water droplets will not adhere to the transmission components of the opening driving part.
[0057] (5) Since the waterproof cover is only provided above the opening driving part, the state of the opening driving part can be visually confirmed from outside the machine without removing the waterproof cover, which is convenient for machine maintenance.
[0058] (6) Since a bag-like folded part is provided on one end of the horizontal baffle and the weaving shaft baffle, the support member is inserted from there to be installed, so the installation is simple and reliable. In addition, since only the upper part of the horizontal baffle and the weaving beam baffle are fixed, and the lower part is hung down by its own weight, it can be easily opened for operation when checking the inside of the machine or for maintenance.
[0059] (7) The upper tank and the middle tank are provided with partition walls at the peripheral part, so the water is blocked and does not leak to the outside.
[0060] (8) Since the upper slot is divided into 2 parts in the left and right direction, it can be disassembled freely, so it can be disassembled and assembled as needed, which is convenient for machine maintenance.
